Green polyp toadstool hates Zooplanktos-M?

[Retro Heat]

It looks like my Green Polyp Toadstool hates it when I add Bright well Aquatics Zooplanktos-M. It pretty much closes up even if I only add 2 drops to my 15g tank. I've been adding it to feed my Feather Duster worm and I noticed that my pods have been taking off as well. But my toadstool hates it so I guess I have to stop using it. Will my Feather Duster be ok? I currently feed my clowns frozen brine/spirulina or new life spectrum pellets soaked in Bright well AminOmega.

I don’t target feed my feather dusters and they are fine. However I have a larger aquarium so probably feed more. I also use Aquavitro Fuel twice a week. No issues with my toadstools or other leathers.
